MIAMI (CBSMiami) – Isaias, now a Tropical Storm, could restrengthen to hurricane strength overnight as it inches slowly closer to Florida’s southeast coast.

At 11 p.m. Saturday, the center of the storm was 80 miles southeast of Fort Lauderdale and 105 miles southeast of West Palm Beach.

It was moving to the northwest at 9 mph with sustained winds of 70 mph.

Tropical storm force winds extend outward up to 115 miles from the center.

A general northwestward motion with some decrease in forward speed is expected for the next day or so, followed by a north-northwestward motion by late Sunday.  A turn toward the north and north-northeast is anticipated on Monday and Tuesday with an increase in forward speed.

On the forecast track, the center of Isaias will approach the southeast coast of Florida early Sunday and move near or along the east coast of Florida Sunday and Sunday night.  On Monday and Tuesday, the center of Isaias will move from offshore of the coast of Georgia into the southern mid-Atlantic states.

Some restrengthening is possible, and Isaias could regain hurricane strength early Sunday.  Slow weakening is expected to begin Sunday night and continue through Monday..
